This application scenario can not be fully met by other IoT communication technologies, which is also the original intention of LoRa IoT Technology ... LoRa is based on linear frequency modulation spread spectrum, which not only maintains the low Power consumption characteristics of Signal spectrum modulation but also significantly increases the communication distance ... The emergence of LoRa can well solve the application scenarios of long-distance, low Power consumption, and small Signal in the transmission of the internet of things.
